To all whom it may concern: H V t known that I, J OHN SCHADE, a citi-"ze 1 '1 ofthe United States, residing at the of'I-Iolyokd' in thecounty of Hampden' and stat'eiof' Massachusetts, have invented" certain5 new and useful Improvements in Unitary Telescoping'Elements andLocking'ltleans; 'andI do declare the followin'ggto be a full, clear,and exact description of the invention, such as will enable othersskilled the artfto which it appertains to r, makeand usethe s'aineQ'This inventionrelates to unitary telescopelement s and locking meanstherefor, ando has forfits L'object'to provide a very simple'fia di,ctive' device'of this description, }and fur,thermore,-to equip thetelescoping ,elenl'entsfwith locking 'means which shall be positive andautomatically operated by the compression of said elements.

Further objects of the invention will appear from the description tofollow supple exited by the accompanying drawing, in

which-* 4 'Figure '1 is a broken plan view illustrating the invention asapplied to a loose leaf der.- f

' Figure 2 is a section at the line 22 of Figure 1, the section beingtaken through the binder elements of the loose leaves only- Figure 3 isa similar section taken at the line 3-3 of Figure 1* Figure 4 is a viewillustrating the elements of the improvement in detached conditionpreparatory to assembly- Figure 5 is a detail broken view partly insection of the inner telescoping elementr Figure 6 is an elevation,partly broken, of the invention in its simplest form, and

Figure 7 is a plan view broken away of one of the loose leaves.

Similar numerals of reference denote like parts in the several figuresof the drawing.

1, 2, are the usual binder elements which may be made of wood or anysuitable material each having secured thereto the usual complementalhinge element 3, 4:. 5, 6, are respectively the inner and outertelescoping elements, the former having one extremity externallythreaded and closed by a plug 7 having a slot 8, the function of whichlatter will be hereinafter described. The lower therewith a detent'9.

'The outer telescoping element} Ghas' an extremity of inner elongatedgate 10 which opens 'through'thej outer extremity 1 of such element, onewall extending therealon'g" of said gate having ratchet teeth 11.

' 12 is a threaded screw cap which is driven" on the plug end of thee1ement 5 ,"and'13-is an end cap having prongs '14'ex te'nding i'nwardlytherefrom, and also having secured P oje ti n ii ly and;

thereto a spindle 15 inwardly therefrom.

'16 is a coil spring whichis assembled around the spindle 15 oneextremity 17 o f the springbeing anchored artfund 011G P 10 14 while theother extremity- 18 isancliora within the slot 8 of the plug 71 Inassembling'the parts of the imprbve:

ment the inner element 5 is tnrustnp a ny through the elementfi untilthe threaded end of the former element extends beyond; the

latter element, and the screw cap 12is then driven on the threaded end.Thecoil spring 16 is placedwithin the telescoped members and itsextremities anchored inthe manner before described. V

In applying'the device to the"' bind er'elements 1, 2, the outertelescoping element 6' is first then inserted through'the binder 'elements, and the inner telescoping element 5 inserted through the element6, and the screw cap 12 driven on the part 5. spring 16 is then insertedand anchored in the manner before described, and the end cap 13 thrustinwardly to compress the spring, and given one or two turns so as towind the spring for producing a torsional effect of the latter. When theend cap has been thrust inwardly to completely compress the spring itwill be housed within the outer face of one of the binder elements, theelement 2 in the present instance, and the prongs 14 will have beenthrust beyond the inner face of the binder element and clinched over thesame, as more particularly shown at Figure 2 of the drawings.

These prongs 14: pass through grooves 19 formed in the element 2 so thatthe end cap 13 is prevented from turning and the spring in n ismechanical ekpedi ents, and the m'irention 1.
